IMPROVEMENT IN HORSE HAY-FORKS.

Specification forming part of Letters Patent No. 189,095, dated April 3, 1877; application filed November 11, 1876.

specification Figure 1 is a side elevation of my improved fork. Fig. 2 is a central vertical section on line 00 w in Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention relates to the class of forks used for loading and unloading hay and other similar substances by means of horse-power.

The invention will first be described in con nection with the drawing, and then pointed out in the claim.

Referring to the drawing, A is the central tubular tine, and B B are the lateral tines. O is a tubular plunger, that fits into the tine A, and is provided at its'upper end with the eye or hook d. and is plugged at its lower end, and provided with ears, between which the barbs e are pivoted. D is a spring, clamped to the tine A by the band g and screw h, and

provided with a catch-pin, i, which passes through the disengaging-lever E and side of the tine A into a hole in the plunger 0. The lever E encircles the tine A, and rests under the spring D, and is held in place by the catch-pin z. The free end of this lever is bent upward, and provided with a small pulley, j. F is a key, that passes through a mortise in the tine A, and through a slot in the plunger 0, for limiting the motion of the said plunger. The end of the key F is bent over the front of the tine A, and formed into an eye for attaching the disengaging-cord k, which runs over the pulley j.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A horse hay-fork provided with a key, F, bent over the front of tine A, and formed into an eye for receiving the disengaging-cord, substantially as shown and described.
